Title: Method and apparatus for 2-stage phase control
Inventor: TAKASAGO AKIRA
IPC: H03L7/00
Filed: 1990-02-23
Abstract: PURPOSE:To reduce a time required for the correction of a phase difference by comparing the phase of an input signal with that of an output signal, generating a voltage in response to the detected phase difference, and applying the voltage to an oscillation means. CONSTITUTION:A level measurement section 1 converts the phase difference of an input signal (a) from an input terminal 9 with that of the selection signal from a selector 8 into the voltage through a built-in integration device and when the phase difference exceeds a prescribed value, the voltage is changed. That is, the phase of the input signal and the phase of the output signal are compared to detect a phase difference and when the detected phase difference is smaller than a prescribed value, the voltage based on the detected phase difference is generated and sent to an oscillator 2, and when the detected phase difference is larger than the prescribed value, the voltage based on the expanded phase difference is generated and sent to the oscillator 3. Thus, the convergence of the phase of the output signal when the phase difference of a prescribed value or larger is quickened.

Title: Fluorescent screen forming method of color picture tube
Inventor: OKADA SHIGEKAZU
IPC: H01J9/227
Filed: 1978-04-18
Abstract: PURPOSE:To form a metal coat of mirror surface which prevents blister and features a high reflexibility with no crack by tiering up the water swelling polyvinyl alcohol film, acryl resin film and metal film onto the fluorescent screen. CONSTITUTION:Thin film 25 of water swelling polyvinyl alcohol featuring a lower decomposition temperature then acryl resin 23 is provided on the layer composed of fluorescent substance 22 before formation of resin 23, thus eliminating exposure particle 22' of the fluorescent substance completely. Then metal film 24 is evaporated and burnt. With this burning, the heat decomposition is caused to film 25. As a result, the extremely this pinhole is caused to the metal film, and the gas is  discharged to prevent the blister occurrence. As film 25 is not dissolved easily into  the water, no elution of the film is caused even with coating of the water soluble acryl emulsion solution in the next process. Thus, a high adhesion is secured between film 25 and the acryl resin film with a thin thickness since the surface of  film 25 is flat. As a result, a high-luminance fluorescent screen can be obtained  with the metal film featuring a high reflexibility coated.

Abstract: PURPOSE:To offer a manufacturing method of an optical fiber handle which is capable of  easily obtaining a desired sectional shape in an optical transfer element, and is capable of  sending an effective light quantity or image as much as possible in a limited area. CONSTITUTION:A photoconductive strand 3 is obtained by making coating glass 2 having a  comparatively small refractive index tightly adhere to the circumference of core glass having  a large refractive index, and this strand 3 is collected in large quantities, and also is bundled  as shown by a code 3' so that it forms a prescribed sectional shape conforming with an object  space when it has been elongated. Subsequently, an assembly body 5 is obtained by placing an outside circumferential material which can be removed by posttreatment, for instance, a glas  rod 4, on its outside circumference, so that the whole sectional shape becomes round. The glass rod part 4 of the assembly body 5 is heated and softened under reduced pressure and is  made to tightly adhere as one body, by which an outside circumference 4' is formed. In this  state, the bundle part 3' of the photoconductive strand 3 is heated and elongated until it  becomes size conforming with an object space, and after that, the outside circumference 4' is  melted out by a dilute NaOH solution. In this way, an optical transfer element forming a  prescribed sectional shape, that is, a conduit 6 is obtained, and the conduit 6 is incorporated  in an endoscope tubular body 7, for instance, as a light guide.

Inventor: ONO MASAYOSHI
IPC: H01L23/522
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To reduce the transmission loss even when a semiconductor substrate such as a low resistance Si substrate used for a conventional Si-IC is in use by forming a strip conductor through stacked air bridges in a propagation direction of a radio wave and forming an air layer between the strip conductor and the semiconductor substrate. SOLUTION: A microstrip line is made up of an air bridge 1, a strip conductor 2, a semiconductor substrate 3 and a ground conductor 4. In a conventional high frequency line, an electric field has a vertical component in a region between the strip conductor and the ground conductor 4, the propagated electric field is concentrated between the strip conductor 2 and the ground conductor 4 opposed to each other. Thus, the transmission loss is increased in a substrate with a high device loss such as a low resistance Si substrate used for a conventional Si-IC.  However, in this high frequency line, the strip conductor 2 is formed by stacking plural air-bridges in the propagation direction of a radio wave and air layer is provided between the conductor layer 2 and the substrate 3, the electric field between the conductor 2 and the other conductor 4 is spread in an air layer to reduce the dielectric loss by the substrate.

Abstract: PURPOSE:To set the temperature when evaluating the temperature characteristic of an IC and observe the input wave-form at the lead section of the IC by inserting or removing the IC by the expansion or shrinkage of the bin of an IC socket and exposing and fixing the IC on the surface of the socket. CONSTITUTION:When an IC 200 is put at the preset position of the recess 14 of an IC socket 10 for its insertion, the IC 200 pushes the center end 13b of a stopper 13 and depresses the stopper 13. When the stopper 13 is lowered, the hooking of the tip 13a is released, the pin 11 is extended in the horizontal direction and pinches and fixes the IC 200, the lead 201 of the IC 200 is brought into contact with the pin 11 of the socket. When the IC 200 is to be removed from the socket 10, the pin 11 is pushed and retreated by a finger or the like, and the IC 200 is removed. When the pin 11 is retreated to the fixed position, the stopper 13 is operated, thus the pin 11 is not extended again until the IC 200 is inserted into the socket again.
